Hybrid OpenMP MPI Benchmark project ("homb")
This is the Hybrid OpenMP MPI Benchmark project ("homb")
This project was registered on SourceForge.net on May 16, 2009, and is described by the project team as follows:HOMB is a simple
benchmark based on a parallel iterative Laplace solver aimed at comparing the performance of MPI, OpenMP, and hybrid codes on SMP and
multi-core based machines.
NAS PARALLEL BENCHMARKS
These are parallel implementations using OpenMP, High Performance Fortran (HPF), and Java, respectively. They were derived from the NPB-serial implementations released with NPB 2.3, after some additional optimization. These implementations, which include the improved serial codes, were previously known collectively as the Programming Baseline for the NAS Parallel Benchmarks (PBN).
A set of multi-zone benchmarks based on the single-zone NPB 3 has been added. The implementations include both serial and parallel versions. They are meant for testing the effectiveness of multi-level and hybrid parallelization paradigms and tools. The parallel implementation uses hybrid parallelism: MPI for the coarse-grain parallelism, and OpenMP for the loop-level parallelism.
